1.5" Lustrous Cassiterite Crystals with Goshenite? - China
This 1.5" wide specimen features an aggregation of translucent cassiterite crystals and what appears to be a goshenite crystal near one edge. It comes out of the Amo Sn deposit in Yunnan, China, a location know to produce exceptional cassiterite crystals. This site isn't known to produce goshenite, though various beryl varieties are known to form in association with goshenite. There also appear to be bladed calcite crystals scattered throughout the matrix.
It has been mounted to an acrylic display base with mineral tack.

About Cassiterite
Cassiterite is a dense, lustrous tin oxide mineral (SnO₂) best known as the world’s primary ore of tin and prized by collectors for its striking crystal forms. Typically appearing in shades of brown, black, or reddish-brown, cassiterite can also occur in beautiful honey-yellow to near-colorless crystals when impurities are low. Its exceptional hardness and high refractive index give well-formed crystals a brilliant, almost metallic sparkle, especially in twinned or pyramidal habits. Cassiterite commonly forms in hydrothermal veins, pegmatites, and alluvial placer deposits where its heavy, durable grains accumulate over time. Found in classic localities such as Bolivia, China, DR Congo, England, and Cornwall, this mineral holds both immense historical significance—fueling centuries of tin production.
